  1. Ignition switch ON and battery voltage is 10.5 V or more

  2. Any 2 or more of following signals are ON simultaneously.


    • (NSW, P, N) input signal

    • R input signal

  2. All switches are OFF simultaneously


    • NSW input signal

    • P input signal

    • R input signal

    • N input signal

    • D input signal

    • B input signal

  3. 60 seconds

  4. 2-trip detection logic

  1. Ignition switch ON and battery voltage is 10.5 V or more

  2. When any of following conditions is met, the S (SDSW) signal is ON


    • NSW input signal is ON

    • P input signal is ON

    • R input signal is ON

    • N input signal is ON

  3. 2 seconds

  4. 2-trip detection logic

MONITOR DESCRIPTION

For security, the park/neutral position switch detects the gearshift position so that engine can be started only when the vehicle is in the P or N shift position.

When the park/neutral position switch and shift lock control unit assembly (transmission control switch) send more than one signal at a time from switch positions P, R, N, D, S (SDSW) or B, the ECM interprets this as a fault in the switch. The ECM will turn on the MIL and store the DTC.

  6. PERFORM INITIALIZATION

    Note


    • Performing reset memory/initialization will clear the learned values of both the yaw rate and acceleration sensor (deceleration sensor 0 point calibration) and the CVT oil pressure (CVT oil pressure calibration). Make sure to perform reset memory, yaw rate and acceleration sensor 0 point calibration, and CVT oil pressure calibration when replacing any of the parts shown in the following table:

      Replaced Part

      • Continuously variable transaxle assembly

      • ECM

      • Oil pressure sensor

      • Yaw rate and acceleration sensor

    • After reset memory, always perform yaw rate and acceleration sensor (deceleration sensor 0 point) calibration first, and then the CVT oil pressure calibration.

    • Always perform the 0 point calibration with the vehicle on level ground.

    • Do not shake or vibrate the vehicle during the 0 point calibration.
